Application filed November 15, 1913. a Serial No. 801,219.

To all whom it may concern.

Be it known that I, J osnrn VALIND, a citi- Zen of the United States, residing at Gladstone, in the county of Delta and State of Michigan, have invented certain new and useful Improvements in \Vrenches, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to new and useful improvements in wrenches and the primary object of my invention is to provide an adjustable wrench that can be quickly and.

easily manipulated to place the adjustable jaw of the wrench at a desired position upon the shank relatively to the fixed jaw thereof, this object being accomplished by means of a mechanism which is entirely concealed within the shank.

Another object of the invention is the provision of a wrench of the above character which will possess advantages in points of efficiency and durability, is inexpensive of manufacture and at the same time is simple in construction and operation.

With the above and other objects in view, the invention consists in the novel features of construction and the combination and arrangement of parts to be hereinafter more fullydesoribed, pointed out in the claim and shown in the accompanying drawings, in which- Figure 1 is a side elevation of a wrench constructed in accordance with my invention; Fig. 2 is a partial detail longitudinal sectional view; Fig. 3 is a transverse sectional view taken on the line 8-3 of Fig. 1; Fig. 4 is a transverse sectional view taken on the line H of Fig. 2; Fig. 5 is a transverse sectional view taken on the line 55 of Fig. 2.

Referring more particularly to the drawings, 1 indicates the rigid shank of my improved wrench having a handle portion 2 formed integral at one end thereof and a rigid jaw 3 formed at the other end thereof. The shank as clearly illustrated in the accompanying drawings is preferably formed flat and the handle member 2 which is formed integral therewith is preferably of oval shape in form, as illustrated and is pro vided upon one side thereof with oppositely disposed shoulders 4: forming a reduced portion 5 in which is provided a recess 6 to receive a screw 7 provided with a substantially rectangular bore 8. The reduced portion 5 is provided with a longitudinalbore 9 which is adapted to communicate with the recess 6 and arranged in alinement with the central bore 8 of the screw 7. A substantially rectangular rod 10 is arranged within the bores 8 and 9 and 13 provided upon its outer end with a knob 11 whereby the same may be readily turned when desired to impart motlonto thesleeve 6. Thereduced portion 5 is provided beyond the recess 6 with a bore 12 in which the tapering end of the rod 10 1s dlsposed so as to prevent lateral movement of the screw? when the rod is arranged in position.

Arranged alongside the rigid shank 1 is a movable shank 13 which is preferably of the same form as the rigid shank and provided at its outer end with a jaw 14- and is further provided at its inner end with a substantially semicircular portion 15 having a concave recess 16 upon the inner face thereof which is provided with the screw threads 17 adapted to co-act with the screw 7 whereby upon rotation of said screw the movable jaw 14 will be adjusted toward or away from the rigid jaw 3. Spaced sleeves 18 are carried by the movable shank 13, one of said sleeves being arranged adjacent the jaw 14: and adapted to inclose the shank portions 1 and 13. The other of said sleeves is carried by the inner end 15 of the movable shank and is adapted to inclose the handle portion 2 of the rigid shank so that the two shanks may be securely held together.

From the above description taken in connection with the accompanying drawings, it will be readily apparent that when it is de sired to adjust the movable jaw 1a with respect to the rigid jaw 3, the knob 11v is grasped and the screw 7 rotated, the threads thereon co-acting with the threads 17 formed in the concave recess 16 whereby the movable jaw will be quickly and readily adjusted tohavingqai central'fb'orecommunicating-With the bore in the handle, a; movable shank having" a aw opposed to the-rigid jaw; the inner edge? of said-handle member having a substantially convex surface; said movable [shank having a concave longitudinal recess adapted to receive the convex portion of the Copies of this patznt-"may- 'b e obtained 'for handle member, screvv threads formed ion the ends of saidoonoave recess and, adapted to ooa ct with the screw, and a rod arranged Within the bores formed ln'sald screw-and handle member vand' provided With a knob whereby said screw may be rotated to adj 11st the movable jaw With respect to the rigid jaw, and a metallic bandgyencircling said handle member vand movable shank, whereby. to prevent lateral movement ofeeither "member.
